Moving Adaptec Raid 1 Array - Gone very wrong

I have moved a 2 disc 147gb SCSI Raid 1 array from a Dell Prec Controller (Adaptec) to a new Adaptec SCSI Host Raid system but it did not work properly.

The Host Raid Bios picked up 2 seperate 147gb discs so I told it to copy one to the other and create a raid 1 array. I then booted into Windows while the array reconstructed and initialised the disc, it came up as containing no partitions :(

The array with problems is not the boot drive and I did not specify it as bootable. I would have thought the partition should be viewable while the second disc rebuilds but it isnt. The problem gets worse because I think the old Perc controller was only using 127Gb of the disc due to the firmware not supporting >127gb. Anyone know how to recover this array?

First just wait until the array has rebuilt. This can sometimes be enough to help. If not, make sure you have enough diskspace on a further disk to take the data on your array, then visit the following site to get recovery software:

You can get some real whonky partitions and formats on drives that are incorrectly sized by the BIOS.  Unfortunately, these can't be read by standard Windows systems when moved.  The only real hope is a raw recovery program.

If I was to put the two drives back in the original server, do you think it would be able to read them still?

I'd only try that with one drive, not both, but first definitly wait until the rebuild has finished.

It might read them.  Then again, the damage may already be done.  I'll cross my fingers for you.

Rindi,

I assume Getback NTFS is what I need because this is a Raid1 array. Will Getback write anything at all to the dirve? (Ie. Is it a good idea to try Getback before trying to insert drive back into old machine?)

No, getdataback (or also raid reconstructor from the same site) don't write anything to the bad drive. For that reason you need the extra space I mentioned above. The trial version of getdataback will be able to scan your HD and when done, will show you the files it can recover. If you see those you need you can register the software and then you can actually recover the files. I think you can also recover files without registering, but then you need to recover every file alone.

I've had great success with OnTrack's Easy Recovery Pro.  GetDataBack hasn't been as good at recovering stuff for me.  Note I said, "...for me."  Others have had the opposite experience.

I have used Ontrack's Excahnge recovery software and that works well (Apart from no Public folder support) but I bet its a fair bit more money than the Runtime software. I ran the demo of the Runtime soft while the array is still rebuilding. It found one physical disk of the two (I guess the other is hidden from OS during rebuild) and was finding valid files but looked like it was gonna take a long time so I cancelled it and will wait until the rebuild completes.

True, the scan can take a long time.

Recovered all 60Gb of data quickly with GetDataBack NTFS. Most points to Rindi and a few to others for info that maybe useful to me in future.
